In the cap l0, at a convenient Between the wheel on the axle and the end point, I make a hole 2l, by which a wrench of the axle I turn a journal IG.

or disk-shaped, and on two sides has bent I am aware that axle-boxes have been made with a cage and a series of rollers revolving within a sleeve, and I do not therefore lay claim to the broad principle of roller-bearings as applied to devices for taking up endthrust; but

What I do claim, and desire to obtain Letters Patent of the United States for, is-

l. In a device for taking up end-thrust of car-wheels, the combination of an axle and fixed Wheel revolving in a sleeve containing a cageand rollers, pivoted by a fulcrum to Y1the axle-box, combined With a ball playing in a pit in the end of the said axle, which said ball plays in a similar pit in the fulcrumplate attached by a collar and horizontal pin to the hinged cap on the end of the axle-box, all as and for the purpose set forth and de scribed.

2. In a device for taking up end-thrust of car-wheels, the combination of an axle, fixed wheel, rollers, cage, sleeve, fulcrum, fulcrumseat, and axle-box, with a ball-bearin g on the end of the said axle playing in a pit in the end of such axle, combined With a fulcrumplate pivoted by the fulcru n1 on the center of the plate to a sliding collar having a fore-andaft motion, moving on the central piu of the K hinged cap of the axle-box and prevented from rotating by the Wedges set in the mortise of the said collar and a similar' one in the said pin, all as and for the purpose set forth and described.

3. In a device for taking up end-thrust in car-Wheels, the combination of a hinged cap to the axle-box, having a central pin mortised, with a rect-angular longitudinal slot, combined with a collar fitting over the pin, having a similar mortise to the one in the pin, and which said collar carries a series of wedges designed to take up the slack by adjusting the nuts at the end of the same, With the fulcrum-plate and end ball and axle with a fixed Wheel, all as and for the purpose set forth and described.

4. In a device for taking up end-thrust in car-Wheels, the combination of the axle and fixed Wheel, with a ball rolling in a conical or spherical pit in the end of said axle, combined With a fulcrum-plate having a correspending pit or flat surface, against which the ball of the axle runs with the collar, pin, and take-up Wedges, all as and for the purpose set forth and described.

5. In a device for taking up end-thrust in car-Wheels, the combination of the axle-Wheel, cage, rollers, fulcrunrseat, and axle-box, cornbined with the fulcrum-plate, collar, Wedges, pin, and the hinged cap provided with a hole in the lower face of the said hinged cap to allow of the tightening of thenuts on the said Wedges, all as and for the purpose as set forth and described.

In testimony whereof I have hereunto set myhand this 9th day of November, A. D. 1889.
